If you don't use the app store, you can still install the xcode command line tools with the xcode-select command. I didn't bother signing in with an Apple account on my personal Mac.
I can't imagine those working too well these days. None of my cards have raised numbers, they'd make a completely blank impression. They have probably been completely phased out in the UK.
I think they mean that companies rarely update their status pages to reflect reality (for instance, AWS outages are rarely shown on their own status pages). This is often by design, company policy, or a desire to save face.
It's true that some planes fly on leaded fuel, but commercial airlines generally do not. It's only piston engine planes that fly on leaded AvGas, all jet aircraft including tubroprops fly on fuels like Jet A (https://en.wikipedia.org/wiki/Jet_fuel)
Another day, another gadgetbahn. It's hard to tell from their website exactly what problems they're trying to solve. They seem to have taken all of the worst aspects of monorail style operations, the relative complexity of maglev, and the vendor lock-in of a gadgetbahn and have just run with it.
Off the top of my head:
From their rolling (gliding?) stock concepts it looks like they're targeting the automated metro system market, think London DLR or Vancouver Skytrain. With these system top speed isn't really the issue as you'll be constrained by acceleration and stop spacing. Better gains can be had in this space by building better signalling systems, allowing the trains to run at higher frequencies.
All of their marketing materials show the trains going in perfect straight lines. A lot of other monorail systems are constrained by this, because building switches for monorails is hard. Throw maglev into the mix and I can't imagine the problem gets any easier.
They focus a bit on ease of construction with the elevated rail segments being made of pre-cast concrete sections. I'm faily certain any modern elevated train guideway is also made of pre-made sections on a production line. They're trying to sell normal as some kind of innovation.
All the usual gadgetbahn things seem to apply as well. TSB goes bust? Good luck getting new rolling stock. Want to integrate this service with existing stations and track? Nope, it's all bespoke. Want to get rolling stock from a different supplier that can meet your local needs better? Good luck with that one. Nobody else buys this system, so it remains expensive forever? Sucks to be you.

That would apply for most uses of software, wouldn't it?

I've encountered variations of this problem at places I have worked in. Education goes a long way to solving this, and this example of simple usage of (A)GPL software is easy enough to explain with examples.
Why is that unfortunate? Unless you're looking to make proprietary changes to Grafana Oncall and host it as a SAAS, it's the same as running any other GPL software.
People are more likely to avoid doing business with you if you call yourself a pyramid scheme. Calling youself a "multi-level marketing" business sounds far more benign.
